Affiliate Plugin - Process for getting paid

So far,in my short time here at WPMU, this plugin gets the award for least documentation for a plugin that seems to require a lot of steps to setup. I"ve read all of the forum posts, looked at the installation guide and found very little. What am I missing?

OK, after a couple hours of trial and error, I think I mostly understand. First question of probably many: The affiliate enters their paypal address, sets up some links and/or banners, users click on those links and buy one of our supporter packages. What's the process for how the affiliate actually gets paid?
